### What Is Dry Lean Concrete (DLC)? - Engineering

2019-7-8 Lean Concrete (DLC) is an important part of modern rigid pavement. It is plain concrete with a large ratio of aggregate to cement than conventional concrete and generally used as a base/subbase of rigid pavement. The compaction of DLC is done under 10 to 12T vibratory roller in the field. Further DLC is mostly made with Ordinary Portland Cement.
